"Thanks to my team for believing in me and supporting me, we had an excellent week. I am really looking forward to the rest of the year," Kerber said in a court-side interview after claiming a first title since her U.S. Open triumph.
"I am playing amazing tennis again and I am just feeling great."
After some tight early service games, Barty double-faulted to hand Kerber the first break and a 3-2 lead, and the German served out the opening set with little trouble.
The second set witnessed an early exchange of breaks before Kerber broke the Australian to love to move 4-3 ahead and picked up her 11th career title when Barty found the net after yet another powerful Kerber forehand.
